1, loach seedling stage: mainly ingested cultivated rotifers, daphnia and other natural bait. 2, loach seed stage: in addition to natural bait, but also need to feed silkworm pupae, pig's blood, wheat bran, tofu dregs, soybean cake, tsetse larvae, fishmeal and other artificial bait. 3, the adult loach stage: mainly ingested rice bran, wheat bran, soya bean dregs, cake meal, soybean meal, corn meal, cooked yams, vegetable stems and leaves and other Plant bait and earthworms, fly maggots, snail meat, animal offal, silkworm pupa powder, blood meal and other animal bait.

First, what the domestic loach eat

1, loach seedling stage

Before the loach seedling pond, every 100 square meters of water sprinkled with 0.5-0.75kg of soybean milk, sprinkled 3-4 times, cultivate the rotifers, fleas and other natural bait for loach to feed on.

2, loach seed stage

(1) Cultivation of about 20 days, loach seedling development to loach seed stage, in addition to cultivation of natural bait, but also need to feed fishmeal, silkworm pupae, pig's blood, bran, tofu dregs, soybean cake, tsetse larvae and other artificial bait.

(2) When feeding bait, wheat bran, soybean cake, miscellaneous fish, blood meal and a small amount of flour should be mixed to make granular bait, in which the ratio of animal bait to plant bait is 5:3.

3, adult loach stage

Plant bait mainly includes rice bran, wheat bran, soybean dregs, cake meal, soybean meal, corn meal, cooked yams, vegetable stems and leaves, etc., and animal bait mainly includes earthworms, tofu dregs, soybean cake, tsetse larvae and other artificial bait. The main bait is earthworms, fly maggots, snails, animal offal, silkworm chrysalis powder, blood meal, etc. The ratio of the two is 2:3.

Second, how much water depth is suitable for loach breeding

1, in summer, when the water temperature is more than 25 degrees Celsius, put loach splash seedling water depth is maintained at more than 70cm. Spring and fall season, the water temperature does not exceed 25 ℃, put the loach water flower seedlings in the water depth control in about 50cm. Subsequent to the growth of loach, gradually deepen the aquaculture water level, but should not exceed 100cm (Taiwan loach, aquaculture water depth is generally maintained at more than 100cm).

2. In summer, the temperature is too high, once the water level is shallow, it is easy to lead to the pond water temperature is too high, and the loach's desire to eat decreases. In winter, the temperature is too low, once the water level is shallow, it is easy to lead to a decline in the thermal insulation capacity of the water body, which is not conducive to the loach winter.

3, the loach has the habit of jumping out of the water, once the water level is too deep, it will lead to the loach in the process of jumping out of the water to consume too much energy, which is not conducive to the loach fertilization.
